Cogging torque influences the control precision of permanent magnet motors used in actuation systems. This paper provides a rigorous analytical prediction method, easy to use in an optimization process. It relies on the fact that the magnetic energy variation due to one slot can be expressed by a coefficient k0 multiplying at the slot location the square of the airgap magnetic field generated by the magnets computed without taking the slotting effect into account.
